Britain's Got Talent will not be investigated by Ofcom after outfits worn by judges Amanda Holden and Alesha Dixon sparked complaints from viewers.

The media watchdog received 19 complaints about the revealing nature of dresses worn by the two female judges during the second live semi-final of the ITV talent show.

Dixon took to the stage wearing a revealing jumpsuit from Sergio Hudson, while Holden wore a metallic gown from Kaufman Franco with a plunging neckline.

An Ofcom spokesperson said: "We assessed a number of complaints about the suitability of clothing worn by two female judges before the watershed, but won't be taking the matter forward for investigation.

One viewer asked whether the dress was "Debenhams curtains", another compared her fashion to Dixon, wondering: "Has Alesha just given up this series? Her outfits aren't coming close to yours Amanda."

The outfit choices worn by both judges for the final of 2015's Britain's Got Talent also drew complaints.

Holden wore a blue dress from designer Tony Ward, which she described on Twitter as a "Frozen meets Cinderella dress", while Dixon wore a floor length black dress with a plunging neckline and slit from mid-thigh.

Some 89 viewers complained to the watchdog following the 2015 final - while more contacted ITV - saying that the pair's racy outfits were "inappropriate" for a family show.

Ofcom later confirmed that after assessing the complaints it would not investigate, because the dresses were not sexualised.

"In our view, the dresses appropriately covered the judges and they were not portrayed in a sexualised way," a spokesman said.
